阅读更多关于 What is a Proxy in Doctrine 2?

I just finished reading all the Doctrine 2 documentation, I started my own sandbox, I understood most of the principes, but there is still a question and I couldn't find any complete explanation in the doc. What are Proxy classes? When should I use them over entities? As far as I understand, proxy classes add a layer to let you add some other features to your entities, but why use a proxy instead of implementing the methods themselves in the entity class? Crozin Proxy objects are used whenever your query doesn't return all data required to create an entity. Imagine following scenario: @Entity

阅读更多关于 Force .NET webservice to use local object class, not proxy class

问题 I have a webservice that I'm calling from a windows forms application (both .NET, both in the same solution), and I'd like my webservice to return a custom object from elsewhere in the project - it's a common object that they both share a reference to, as it's in the third project in my solution.

What are the downsides to turning off ProxyCreationEnabled for CTP5 of EF code first

阅读更多关于 What are the downsides to turning off ProxyCreationEnabled for CTP5 of EF code first

The only way that my WCF service can return classes from a code first model is by setting the ProxyCreationEnable to false using the code below. ((IObjectContextAdapter)MyDb).ObjectContext.ContextOptions.ProxyCreationEnable = false; What are the negative consequences of doing this? One gain is that I can at least get these dynamic types serialized so they can be sent over the wire using WCF. Dynamic proxies are used for change tracking and lazy loading. When WCF tries to serialize object, related context is usually closed and disposed but serialization of navigation properties will
